### Example

The example shows how to manage a middle finger with the `Middle`class.

#### Create a middle finger with a constructor

```csharp
// Create a middle tip joint with the specified 2D position and 
// 3D position.
FingerJoint middleTip = new FingerJoint
(
    FingerJointType.MiddleTip,
    new Vector2(3, 3),
    new Vector3(0.3f, 0.3f, 0.3f),
    new Quaternion()
);

// Create a middle DIP joint with the specified 2D position and 
// 3D position.
FingerJoint middleDIP = new FingerJoint
(
    FingerJointType.MiddleDIP,
    new Vector2(3, 3),
    new Vector3(0.3f, 0.3f, 0.3f),
    new Quaternion()
);

// Create a middle finger with the specified middle joints.
Middle middle = new Middle
(
     new Dictionary<FingerJointType, FingerJoint> 
     {
         { FingerJointType.MiddleTip, middleTip },
         { FingerJointType.MiddleDIP, middleDIP }
     }
 );
```

#### Get joint information from a middle finger

```csharp
// Get middle Tip joint.
FingerJoint middleTipNew = middle.Tip;
```
